IMPROVEMENTv IN GRINDERS FOR HARVESTER-CUTTERS.

The Schedule referred to these Letters Patent azz'd making part c'f tho same.

To all whom 'it may concern.-

Be it known that I, WILLIAM B. DEUEL, of' Ithaca, Tompkins county, N ew York, have invented un Improved Hoy-Harvester Knife-,Grinding Machine or Sharpener; and I do hereby deelzne the following is n full und exnot description thereof, retin-ence being had to the zwconlpnnyingdrawings, und to the lelters thereon.

Ligure-1 is an -end view of a. common grindstone, to"whieh my device is attached by its -nrm or fehle.

Figures 2 are views of uly arm or plate, which holds the knives to the stone, at the four yeornels ot the frame. f

Figure 3 is a. view of my axis to the stone, detached to show its structure.

My object in this, as it wais in a similar device, patented to me on the 3d doy of November, 1868, ond nux-nbered 83,7 6T', is to make an attachment that enn be readily adjusted to any ordinary grir'idstone in common use, and in such n manner that the ordinary islet face of -the stone shall be kept' :md used. This. nequires o means of attachment to the common fnime of the stone, und that the knife-holder be adjustable to any one or all of the four eoruels of the stone, in the corners ofthe fronle. y

My niezuis of doing this will be seen as I describe them.

In tlg. 1, A is the griudstone, such as is liu `oommon use;

B is its nxis, mode by me to have screw-threads or other equivalent menus, so tlnit: the cronk C can be attached to either end, at B' or B"; and

- D-is the nrln or plate, by the set-screw E, attached to the sides F or F, and. is thus adjustable to n-ny one of the four corners of the frame F, and thus brings the knives G in reaeh'of the right ongles which the stone presents to the corners ofthe flume.

The knires ore on the usuel rod, and held in the holder H by the hooks l' and l", :nld the holder is adjustable in o slot, L, in the plote I), :nel turns on'a. bolt through the knob J, which is set by the Inn-r K.

In 'tige Z nre seen hoth n side jdetsched view otv the`phlteD, and n. top view ofthe sxnne,ou the stone t'mme.

In figs. 3, the axis B, with ends to nttawlr'the crank, is seen.

The uses of my invention are apparent to those skilled in the nrt 'to which it appertsns;

I elnini` 1. The :u'mngement of the :mn D, formed of the 'horizontai port D,`pmvided Y with slot L, and the two clamping perpendicular pzu'ts D"':md D'", und set-l screw E, in combination with the sides F' und F' of.

aeolnnxon grinds-tone, for the purpose of holding a. harvester-knife holder to :my one one of the corners ofthe stone, for the grinding of the seid knives, sub'- stzuitially'ns set forth.
